Section 2 - Installation
Installation
This section will walk you through the installation process. Placement of the router is very important. Do not place the router in an enclosed area
such as a closet, cabinet, or in the attic or garage.
Before you Begin
Please read and make sure you understand all the prerequisites for proper installation of your new Router. Have all the necessary information and
equipment on hand before beginning the installation.
D-Link DSL-2750B User Manual

Section 2 - Installation
Installation Notes
In order to establish a connection to the Internet it will be necessary to provide information to the Router that will be stored in its memory. For some
users, only their account information (Username and Password) is required. For others, various parameters that control and define the Internet
connection will be required. You can print out the two pages below and use the tables to list this information. This way you have a hard copy of all
the information needed to setup the Router. If it is necessary to reconfigure the device, all the necessary information can be easily accessed. Be
sure to keep this information safe and private.
Low Pass Filters
Since ADSL and telephone services share the same copper wiring to carry their respective signals, a filtering mechanism may be necessary to
avoid mutual interference. A low pass filter device can be installed for each telephone that shares the line with the ADSL line. These filters are easy
to install passive devices that connect to the ADSL device and/or telephone using standard telephone cable. Ask your service provider for more
information about the use of low pass filters with your installation.
Operating Systems
The DSL-2750B uses an HTML-based web interface for setup and management. The web configuration manager may be accessed using any
operating system capable of running web browser software, including Windows 98 SE, Windows ME, Windows 2000, and Windows XP.
Web Browser
Any common web browser can be used to configure the Router using the web configuration management software. The program is designed to
work best with more recently released browsers such as Opera, Microsoft Internet Explorer® version 6.0, Netscape Navigator® version 6.2.3, or
later versions. The web browser must have JavaScript enabled. JavaScript is enabled by default on many browsers. Make sure JavaScript has not
been disabled by other software (such as virus protection or web user security packages) that may be running on your computer.
Ethernet Port (NIC Adapter)
Any computer that uses the Router must be able to connect to it through the Ethernet port on the Router. This connection is an Ethernet connection
and therefore requires that your computer be equipped with an Ethernet port as well. Most notebook computers are now sold with an Ethernet port
already installed. Likewise, most fully assembled desktop computers come with an Ethernet NIC adapter as standard equipment. If your computer
does not have an Ethernet port, you must install an Ethernet NIC adapter before you can use the Router. If you must install an adapter, follow the
installation instructions that come with the Ethernet NIC adapter.

Section 2 - Installation
802.11 Wireless LAN Configuration
All the 802.11 wireless LAN settings may be configured on a single page using the web-based manager. For basic wireless communication you
need to decide what channel to use and what SSID to assign. These two settings must be the same for any wireless workstations or other wireless
access point that communicate with the DSL-2750B through the wireless interface.
Security for wireless communication can be accomplished in a number of ways. The DSL-2750B supports WPA (Wi-Fi Protected Access), WPA2,
and mixed WPA/WPA2. Wireless access can also be controlled by selecting MAC addresses that are allowed to associate with the device. Please
read the section on Wireless Configuration.
Additional Software
It may be necessary to install software on your computer that enables the computer to access the Internet. Additional software must be installed if
you are using the device a simple bridge. For a bridged connection, the information needed to make and maintain the Internet connection is stored
on another computer or gateway device, not in the Router itself.
If your ADSL service is delivered through a PPPoE or PPPoA connection, the information needed to establish and maintain the Internet connection
can be stored in the Router. In this case, it is not necessary to install software on your computer. It may however be necessary to change some
settings in the device, including account information used to identify and verify the connection.
All connections to the Internet require a unique global IP address. For bridged connections, the global IP settings must reside in a TCP/IP enabled
device on the LAN side of the bridge, such as a PC, a server, a gateway device such as a router or similar firewall hardware. The IP address can be
assigned in a number of ways. Your network service provider will give you instructions about any additional connection software or NIC
configuration that may be required.

Section 2 - Installation
Wireless Installation Considerations
DSL-2750B lets you access your network using a wireless connection from virtually anywhere within the operating range of your wireless network.
Keep in mind, however, that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may
limit the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise in your home or business. The
key to maximizing wireless range is to follow these basic guidelines:
1. Keep the number of walls and ceilings between the D-Link router and other network devices to a minimum - each wall or ceiling can reduce your
adapter’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is minimized.
2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a 45-degree angle appears to be almost 3 feet (1
meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Position devices so that the signal will travel straight through a wall or
ceiling (instead of at an angle) for better reception.
3. Building Materials make a difference. A solid metal door or aluminum studs may have a negative effect on range. Try to position access points,
wireless routers, and computers so that the signal passes through drywall or open doorways. Materials and objects such as glass, steel, metal,
walls with insulation, water (fish tanks), mirrors, file cabinets, brick, and concrete will degrade your wireless signal.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise.
5. If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and home security systems), your wireless
connection may degrade dramatically or drop completely. Make sure your 2.4GHz phone base is as far away from your wireless devices as
possible. The base transmits a signal even if the phone in not in use.

Section 2 - Installation
Device Installation
The DSL-2750B Wireless ADSL Router maintains three separate interfaces, an Ethernet LAN, a wireless LAN and an ADSL Internet (WAN)
connection. Carefully consider the Router’s location suitable for connectivity for your Ethernet and wireless devices. You must have a functioning
broadband connection via a bridge device such as a Cable or ADSL modem in order to use the Router’s WAN function.
Place the Router in a location where it can be connected to the various devices as well as to a power source. The Router should not be located
where it will be exposed to moisture, direct sunlight or excessive heat. Make sure the cables and power cord are placed safely out of the way so
they do not create a tripping hazard. As with any electrical appliance, observe common sense safety procedures.
The Router can be placed on a shelf, desktop, or other stable platform. If possible, you should be able to see the LED indicators on the front if you
need to view them for troubleshooting.
Power on Router
The Router must be used with the power adapter included with the device.
1. Insert the AC Power Adapter cord into the power receptacle located on the rear panel of the Router and plug the adapter into a suitable nearby
power source.
2. Push down the Power button, and you should see the Power LED indicator light up and remain lit.
3. If the Ethernet port is connected to a working device, check the Ethernet Link/Act LED indicators to make sure the connection is valid. The
Router will attempt to establish the ADSL connection, if the ADSL line is connected and the Router is properly configured this should light up
after several seconds. If this is the first time installing the device, some settings may need to be changed before the Router can establish a
connection.
D-Link DSL-2750B User Manual

Section 2 - Installation
Factory Reset Button
The Router may be reset to the original factory default settings by using a ballpoint or paperclip to gently push down the reset button in the following
sequence:
1. Press and hold the reset button while the device is powered off.
2. Turn on the power.
3. Wait for 10~15 seconds and then release the reset button.
Remember that this will wipe out any settings stored in flash memory including user account information and LAN IP settings. The device settings
will be restored to the factory default IP address 192.168.1.1 and the subnet mask is 255.255.255.0, the default management Username is “admin”
and the default Password is “admin.”
Network Connections
Connect ADSL Line
Use the ADSL cable included with the Router to connect it to a telephone wall socket or receptacle. Plug one end of the cable into the ADSL port
(RJ-11 receptacle) on the rear panel of the Router and insert the other end into the RJ-11 wall socket. If you are using a low pass filter device, follow
the instructions included with the device or given to you by your service provider. The ADSL connection represents the WAN interface, the
connection to the Internet. It is the physical link to the service provider’s network backbone and ultimately to the Internet.
Connect Router to Ethernet
The Router may be connected to a single computer or Ethernet device through the 10BASE-TX Ethernet port on the rear panel. Any connection to
an Ethernet concentrating device such as a switch or hub must operate at a speed of 10/100 Mbps only. When connecting the Router to any
Ethernet device that is capable of operating at speeds higher than 10Mbps, be sure that the device has auto-negotiation (NWay) enabled for the
connecting port. Use standard twisted-pair cable with RJ-45 connectors. The RJ-45 port on the Router is a crossed port (MDI-X). Follow standard
Ethernet guidelines when deciding what type of cable to use to make this connection. When connecting the Router directly to a PC or server use a
normal straight-through cable. You should use a crossed cable when connecting the Router to a normal (MDI-X) port on a switch or hub. Use a
normal straight-through cable when connecting it to an uplink (MDI-II) port on a hub or switch. The rules governing Ethernet cable lengths apply to
the LAN to Router connection. Be sure that the cable connecting the LAN to the Router does not exceed 100 meters.

Use WPA or WPA2 mode to achieve a balance of strong security and
best compatibility. This mode uses WPA for legacy clients while
maintaining higher security with stations that are WPA2 capable. Also
the strongest cipher that the client supports will be used. For best
security, use WPA2 mode. This mode uses AES (CCMP) cipher and
legacy stations are not allowed access with WPA security. For maximum

Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DSL-2750B. Read the following descriptions
if you are having problems. (The examples below are illustrated in Windows® XP. If you have a different operating system, the screenshots on your
computer will look similar to the following examples.)
1. Why can’t I access the web-based configuration utility?
When entering the IP address of the D-Link router (192.168.1.1 for example), you are not connecting to a website on the Internet or have to be
connected to the Internet. The device has the utility built-in to a ROM chip in the device itself.
Your computer must be on the same IP subnet to connect to the web-based utility.

Make sure you have an updated Java-enabled web browser. We recommend the following:
 Internet Explorer 6.0 or higher
 Firefox 1.5 or higher

Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using a different cable or connect
to a different port on the device if possible. If the computer is turned off, the link light may not be on.

Disable any internet security software running on the computer. Software firewalls such as Zone Alarm, Black Ice, Sygate, Norton Personal
Firewall, and Windows® XP firewall may block access to the configuration pages. Check the help files included with your firewall software for
more information on disabling or configuring it.

Section 4 - Troubleshooting
 Configure your Internet settings:
 Go to Start > Settings > Control Panel. Double-click on the Internet Options Icon. From the Security tab, click on the button to restore
the settings to their defaults.
 Click on the Connection tab and set the dial-up option to Never Dial a Connection. Click on the LAN Settings button. Make sure nothing is
checked. Click on the OK.
 Go to the Advanced tab and click on the button to restore these settings to their defaults. Click on the OK button three times.
 Close your web browser (if open) and open it.

Access the web management. Open your web browser and enter the IP address of your D-Link router in the address bar. This should open the
login page for the web management.

If you still cannot access the configuration, unplug the power to the router for 10 seconds and plug back in. Wait about 30 seconds and try
accessing the configuration. If you have multiple computers, try connecting using a different computer.
2. What can I do if I forgot my password?
If you forgot your password, you must reset your router. Unfortunately this process will change all your settings back to the factory defaults.
To reset the router, locate the reset button (hole) on the rear panel of the unit. With the router powered on, use a paperclip to hold the button down
for 10 seconds. Release the button and the router will go through its reboot process.
Wait about 30 seconds to access the router. The default IP address is 192.168.1.1. When logging in, type in the default User Name “admin,” and the
default Password “admin” then click on the OK button to access the web-based manager.

Appendix A - Wireless Basics
APPENDIX
Wireless Basics
D-Link wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless connectivity within your home,
business or public access wireless networks. Strictly adhering to the IEEE standard, the D-Link wireless family of products will allow you to securely
access the data you want, when and where you want it. You will be able to enjoy the freedom that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals instead of wires. Wireless
LANs are used increasingly in both home and office environments, and public areas such as airports, coffee shops and universities. Innovative
ways to utilize WLAN technology are helping people to work and communicate more efficiently. Increased mobility and the absence of cabling and
other fixed infrastructure have proven to be beneficial for many users.
Wireless users can use the same applications they use on a wired network. Wireless adapter cards used on laptop and desktop systems support
the same protocols as Ethernet adapter cards.
Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in order to use servers, printers
or an Internet connection supplied through the wired LAN. A Wireless Router is a device used to provide this link.
What is Wireless?
Wireless or Wi-Fi technology is another way of connecting your computer to the network without using wires. Wi-Fi uses radio frequency to connect
wirelessly, so you have the freedom to connect computers anywhere in your home or office network.
Why D-Link Wireless?
D-Link is the worldwide leader and award winning designer, developer, and manufacturer of networking products. D-Link delivers the performance
you need at a price you can afford. D-Link has all the products you need to build your network.
How does wireless work?
Wireless works similar to how cordless phone work, through radio signals to transmit data from one point A to point B. But wireless technology has
restrictions as to how you can access the network. You must be within the wireless network range area to be able to connect your computer. There
are two different types of wireless networks Wireless Local Area Network (WLAN), and Wireless Personal Area Network (WPAN).
D-Link DSL-2750B User Manual
121
Appendix A - Wireless Basics
Wireless Local Area Network (WLAN)
In a wireless local area network, a device called an Access Point (AP) connects computers to the network. The access point has a small antenna
attached to it, which allows it to transmit data back and forth over radio signals. With an indoor access point as seen in the picture, the signal can
travel up to 300 feet. With an outdoor access point the signal can reach out up to 30 miles to serve places like manufacturing plants, industrial
locations, college and high school campuses, airports, golf courses, and many other outdoor venues.
Wireless Personal Area Network (WPAN)
Bluetooth is the industry standard wireless technology used for WPAN. Bluetooth devices in WPAN operate in a range up to 30 feet away.
Compared to WLAN the speed and wireless operation range are both less than WLAN, but in return it doesn’t use nearly as much power which
makes it ideal for personal devices, such as mobile phones, PDAs, headphones, laptops, speakers, and other devices that operate on batteries.
Who uses wireless?
Wireless technology as become so popular in recent years that almost everyone is using it, whether it’s for home, office, business, D-Link has a
wireless solution for it.
Home
 Gives everyone at home broadband access
 Surf the web, check email, instant message, download multimedia files.
 Gets rid of the cables around the house
 Simple and easy to use
Small Office and Home Office
 Stay on top of everything at home as you would at the office
 Remotely access your office network from home
 Share the Internet connection and printer with multiple computers
 No need to dedicate office space
Where is wireless used?
Wireless technology is expanding everywhere not just at home or office. People like the freedom of mobility and it’s becoming so popular that more
and more public facilities now provide wireless access to attract people. The wireless connection in public places is usually called “hotspots”.
D-Link DSL-2750B User Manual

Appendix A - Wireless Basics
Using a D-Link Cardbus Adapter with your laptop, you can access the hotspot to connect to Internet from remote locations like: Airports, Hotels,
Coffee Shops, Libraries, Restaurants, and Convention Centers.
Wireless network is easy to setup, but if you’re installing it for the first time it could be quite a task not knowing where to start. That’s why we’ve put
together a few setup steps and tips to help you through the process of setting up a wireless network.
Tips
Here are a few things to keep in mind, when you install a wireless network.
Centralize your router or Access Point
Make sure you place the router/access point in a centralized location within your network for the best performance. Try to place the router/access
point as high as possible in the room, so the signal gets dispersed throughout your home. If you have a two-story home, you may need a repeater to
boost the signal to extend the range.
Eliminate Interference
Place home appliances such as cordless telephones, microwaves, and televisions as far away as possible from the router/access point. This would
significantly reduce any interference that the appliances might cause since they operate on same frequency.
Security
Don’t let you next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning on the WPA security
feature on the router. Refer to product manual for detail information on how to set it up.
Wireless Modes
There are basically two modes of networking:
 Infrastructure – All wireless clients will connect to an access point or wireless router.
 Ad-Hoc – Directly connecting to another computer, for peer-to-peer communication, using wireless network adapters on each computer,
such as two or more D-Link wireless network adapters.
An Infrastructure network contains an Access Point or wireless router. All the wireless devices, or clients, will connect to the wireless router or
access point.
An Ad-Hoc network contains only clients, such as laptops with wireless cardbus adapters. All the adapters must be in Ad-Hoc mode to communicate.

Networking Basics
Check your IP address
After you install your new D-Link adapter, by default, the TCP/IP settings should be set to obtain an IP address from a DHCP server (i.e. wireless
router) automatically. To verify your IP address, please follow the steps below.
Click on Start > Run. In the run box type cmd and click on the OK.
At the prompt, type ipconfig and press Enter.
This will display the IP address, subnet mask, and the default gateway of your
adapter.
If the address is 0.0.0.0, check your adapter installation, security settings, and the
settings on your router. Some firewall software programs may block a DHCP
request on newly installed adapters.
If you are connecting to a wireless network at a hotspot (e.g. hotel, coffee shop,
airport), please contact an employee or administrator to verify their wireless
network settings.

Example: If the router’s LAN IP address is 192.168.0.1, make your IP address
192.168.0.X where X is a number between 2 and 99. Make sure that the number
you choose is not in use on the network. Set Default Gateway the same as the
LAN IP address of your router (192.168.0.1).
Set Primary DNS the same as the LAN IP address of your router (192.168.0.1).
The Secondary DNS is not needed or you may enter a DNS server from your ISP.
